cusmon DEVICE FOR TOOLS AND THE LIKE. 9

Application filed May 9,

This invention relates generally to at tachments for tools such as handmanipulated electrically or air operated polishing tools, and consistsof certain novel features of construction, combinations and arrangementsof parts as will hereinafter be more fully described and particularlypointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a perspective view of. a tool with an attachment embodyingmy invention applied thereto;

Figure 2 is a detailed fragmentaryperspective view of the attachingmember or retainer.v

Figure 3 is a vertical sectional view through the retainer with theresilient annu' lus applied thereto.

Figure 4 is a fragmentary sectional view similar to Figure 3 butshowinga slightly modified construction. 1

Figure 5 is a side elevation of a tool with a slightly modifiedattachment applied thereto.

Figure 6 is, a cross sectional view taken on the line 66 of Figure 5;

Figure -7 is a detailed perspective, View of the attachment showninjFigures 5 and 6.

Tools of the class described are quite heavy and are frequentlydrop'pedor thrown to the floor during the course of aday by workmen infactories. When the floors are of concrete such tools are oftentimesbroken or otherwise damaged when dropped or thrown as described. Thisnecessitates repairs which oftentimes are quite costly and cause delays.7

With the present invention the difliculties just enumerated have beenobviated entirely by the provision of an attachment which may be readilyapplied to such tools and that will cushion them so as to preventbreakage and damage thereto when dropped or thrownupon concrete orsimilar flooring.

Referring now to the drawings, 1 is a hand manipulated electrically orair operated polishing tool having a metallic casing 2, handle 3, andpolishing wheel 4. As usual, the casing 2 has a tubular portion 5surrounding the rotary drive shaft (not shown) of the wheelt, andserving as a handle or grip portion for the operator.

In use, one hand of the operator grips the handle-3 while theother handgrasps the tubular portion 5 of the casing so as to or thrown to thefloor.

guide or hold the wheel 4 in proper position with respect to the work..In the present instance the tool 1 is provided with an attachment 6thatwill effec-- tlvcly cushion the tool so as toprevent 1v breakage ordamage thereto when dropped As shown, this'attachment comprisesa'resilient annulus 7, and an attaching member or retainer 6.

Preferably the annulus 7 is formed of rubberg andihas a substantiallyuniform cross se'ctlon throughout .its length, while the retamcr has asubstantially fiat disk portion 9 attached to the casing '2 adjacent tothe handle 3 and has an outwardly opening channel shaped rim portion 10holding the rubber annulus 7. \Vith this, constructionthe disk 9 may beformed of two sheet metal parts such as shown in Figures2 and 3, or inone part as shown in Figure 4, however, in both instances the disk 9 isprovidedwith a central opening 11 and opposed slots 12 for receiving thecasing 2 and handle 3 respectively, andis provided about said opening 11between said slots 12 with a series of so apertures 13 for receiving theusual bolts 14:

{321i form a standard part of the tool assem- Thus, with theconstruction asdescribe'd,

the attachment 6 may be readily applied to 1 I the tool 1 by merelyloosening and'r'emoving the bolts 14, thenslipping the disk 9 over thehandle 3 and upon the casing 2, and finall adjusting the bolts 14 tosecure 7 the disk rmlyin position upon-the casing.

The tool 1 may then be dropped or thrown upon the floor without beindamaged as theresilient annulus 7 will absorb all shocks and jars andwill adequately cushion and serve as a shock absorber for the casing' 2.

In Figures 5 to 7 inclusive I have shown a slight modification in whichthe attach 'ment comprises a centrally apertured d1sk' 1 20 of rubbersecured to a metal plate 20.

The plate is also centrally apertured and both the plate and rubber.disk are provided with opposed slots similar to the slots 12 a forpermitting the attachment to be secured by the usual bolts 21 to thecasing 22 of the tool. Preferably blocks 23 of rubber are secured to theinner face of the disk 20 at spaced points thereof so as to overlie andcushion laterally extending projections 24 of the casing 22 of the tool.

While it is believed that from the forego ing description, the natureand advantage of my invention will be readily apparent, l desire to haveit understood that I do not limit myself to what is herein shown anddescribed and that such changes may be resorted to when desired as fallwithin the scope ot what 1s clamled.

What I claim as my lnvention is:

1. A shock absorber for tools and thelike comprising a disk having anaperture for receiving the casing of a tool, and shock absorbing meanscarried by said disk.

2. A shock absorber attachment for tools and the like comprising a diskhaving a central aperture for receiving a portion of a casing of a tooland having other apertures for receiving bolts constituting standardparts of the tool, and resilient means carried by said disk so as tocushion the casing of said tool.

,3. A shock absorbing attachment for hand manipulated electricallyoperated tools comprising an annular member attachable to a portion ofthe tool, and means of resilient. material carried by said member so asto project a sufficient dlstance radially from the tool to cushion thelatter when dropped 'or thrown to a floor or the like.

4. A shock absorbing attachment for a hand manipulated electricallyoperated tool having a casing, and a handle secured to the casing at oneend of the tool, comprising means formed of resilient material forcushioning said tool, and attaching means for said resilient meansincluding a member attachable to the casing of said tool, said lastmentioned member having apertures for receiving a portion of the casingand said handle at one end of said casing.

In combination, a tool'having a casing, and a handle at one end of thecasing, and an attachment for said casing including an annulus ofresilient material, and attaching means for said annulus including adisk sleeved upon and secured to a portion of said casing adjacent tosaid handle.

6. In combination, a hand manipulated electrically operated tool havinga casing, provided with an enlargement at one end thereof, and a shock.absorber attachment for said tool including a. disk sleeved upon saidenlargement, and resilient cushioning means carried by said disk.

In testimony whereof I aflix my signature.
